Abstract
A bolt has a pointed end with cutting edges. The cutting edges may have knurls (grooves) or ridges, and may have a spiral arrangement. The bolt may have a convex end, such as a cone end or a curved end. A plurality of bolts may be used as part of a reinforcing bar splice that also includes a sleeve. The bolts engage threaded holes of the sleeves. As the bolts are tightened, they bore into the receiving bar ends, securing the bar ends within the sleeve. Cutting edges on the bolts aid in boring the ends of the bolts into the reinforcing bar ends. Using cutting edges on the bolt ends allows deeper penetration of the bolts into the reinforcing bar ends, without increasing the amount of torque used.
